Survey of non d20 Abilities and Score Generation

[Darkwolf445]

Gamma World, for the first three editions (and probably 4th as well), was the same as D&D/AD&D. i.e. roll 3d6 and add them together. If you were a Pure Strain Human you rolled 4d6 for Int and Constitution. I believe 4th ed was roll 4d6-L.

5th edition was Alternity rules system.
